Researchers design microparticles that can deliver oxygen quickly into the bloodstream

Patients unable to breathe because of acute lung failure or an obstructed airway need another way to get oxygen to their blood—and fast—to avoid cardiac arrest and brain injury. A team led by researchers at Boston Children's Hospital has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood.

Researchers create endothelial cells with blood-brain barrier qualities

The blood-brain barrier -- the filter that governs what can and cannot come into contact with the mammalian brain -- is a marvel of nature. It effectively separates circulating blood from the fluid that bathes the brain, and it keeps out bacteria, viruses and other agents that could damage it.

Nrf2-KEAP1 protein may play a role in diabetic retinopathy

A Wayne State University researcher believes a protein that fails to reach the nucleus of retinal cells may play a role in causing eye disease in people with diabetes.

Formation of blood vessels in tumors attacked from two angles

As soon as they have grown to pinhead size, tumors rely on the formation of new blood vessels - a process which is scientifically called angiogenesis. Interfering with this process (antiangiogenesis) is considered to be a promising approach in cancer medicine. However, those drugs that are already available for preventing the sprouting of new blood capillaries have failed to fulfill the high expectations placed on them.

IntegenX to accelerate commercialization of human DNA identification system with SV acquisition

IntegenX Inc., a privately held company that is a leader in the emerging field of rapid human DNA identification, today announced that it has acquired SV Corp, a wholly owned subsidiary of GE Healthcare Bio-Sciences. IntegenX will leverage SV Corp's products and intellectual property assets to expand its consumables offering and to accelerate the commercialization of its RapidHIT 200 Human DNA Identification System.

Scientist generates mutant version of IL-2 protein to treat advanced cancers

The utility of a naturally occurring protein given, sometimes to great effect, as a drug to treat advanced cancers is limited by the severe side effects it sometimes causes. But a Stanford University School of Medicine scientist has generated a mutant version of the protein whose modified shape renders it substantially more potent than the natural protein while reducing its toxicity.

Simple and accurate device to study malaria

University of British Columbia researcher Hongshen Ma has developed a simple and accurate device to study malaria, a disease that currently affects 500 million people per year worldwide and claims a million lives.

Study aims to achieve early detection of heart disease

With the month of February designated as Heart Health Month, physician-researchers in the Division of Cardiology at the Los Angeles Biomedical Research Institute (LA BioMed) - Dr. Matthew Budoff and Dr. Ronald Oudiz - continue to pave the way with their efforts to develop treatments and therapies for conditions affecting the heart, and to help improve overall heart health.

Researchers derive vessel-forming stem cells from amniotic fluid

Researchers at Rice University and Texas Children's Hospital have turned stem cells from amniotic fluid into cells that form blood vessels. Their success offers hope that such stem cells may be used to grow tissue patches to repair infant hearts.

Intra-arterial technique of stem cell transplantation may enhance functional recovery from TBI

Experiments in brain-injured rats show that stem cells injected via the carotid artery travel directly to the brain, where they greatly enhance functional recovery, reports a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Potential way to block second wave of death from pneumonia treatment

An international research team may have found a way to block a second wave of death that can result from pneumonia treatment.

Excess salt stimulates production of adrenalin and causes hypertension

A review article by researchers at Boston University School of Medicine (BUSM) debunks the widely-believed concept that hypertension, or high blood pressure, is the result of excess salt causing an increased blood volume, exerting extra pressure on the arteries. Published online in the Journal of Hypertension, the study demonstrates that excess salt stimulates the sympathetic nervous system to produce adrenalin, causing artery constriction and hypertension.

Researchers reveal how podocytes may regenerate themselves during normal kidney function

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function.

New laser technique could create tissue scaffolds, microneedles

In the emerging field of tissue engineering, scientists encourage cells to grow on carefully designed support scaffolds. The ultimate goal is to create living structures that might one day be used to replace lost or damaged tissue, but the manufacture of appropriately detailed scaffolds presents a significant challenge that has kept most tissue engineering applications confined to the research lab.

Knife-edge scanning microscopy rapidly maps new blood vessels in organs

Like normal tissue, tumors thrive on nutrients carried to them by the blood stream. The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too. To better understand the relationship between cancer and the vascular system, researchers would like to make detailed maps of the complete network of blood vessels in organs. Unfortunately, the current mapping process is time-consuming: using conventional methods, mapping a one-centimeter block of tissue can take months.

LA BioMed's lead investigator hopes to bring PAH awareness this November

As the month of November kicks off PH Awareness Month, Dr. Ronald Oudiz - lead investigator at the Los Angeles Biomedical Research Institute (LA BioMed) - hopes to bring greater awareness to this disorder that has affected the lives of so many. Dr. Oudiz is a pioneer in this field, having received the 2011 Award for Excellence earlier this year from the Pulmonary Hypertension Association for his dedication to find new ways to treat this often fatal disease.

Scientist granted over $138,000 to explore Vitamin C therapy in sepsis

Sepsis kills more people than breast, colorectal, pancreatic, and prostate cancers combined. Outside of coronary care units, it is the leading cause of mortality in intensive care units. Every year 18 million people worldwide develop this potentially fatal disease. Thanks to a generous grant of $138,238.65 from the Jesse and Julie Rasch Foundation, Lawson Health Research Institute's Dr. Michael Sharpe is exploring a new sepsis therapy using Vitamin C.

Scientists invent new system that uses magnetism to purify hybrid nanoparticles

A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles -- structures that are composed of two or more kinds of materials in an extremely small particle that is visible only with an electron microscope.

Single engineered protein blocks two related angiogenic receptors

Cancer needs blood. In fact, some cancer medications work solely to slow or prevent cancer cells from creating new capillaries, choking off their much-needed blood and nutrient supply to halt the growth of tumors.

New method of delivering growth factors could lead to revolutionary heart treatment

Ever since the Nobel Prize for nerve growth factor was awarded more than 30 years ago, researchers have been searching for ways to use growth factor clinically.
